Hello,
In nRF Connect for Mobile, custom UUIDs show up as unknown, making it difficult to identify them easily.
Is there a way to add custom UUIDs, as can be done for example, on a Mac by adding the custom UUIDs to the "uuid_definitions.json" (located in folder /Users/username/Library/Application\ Support/nrfconnect)?
If not, How do I request an enhancement to nRF Connect for Mobile?
Thank you.
zpm1066 said:As discussed before, an enhancement to nRF Connect for Mobile should resolve the issue. Hopefully the nRF Connect for Mobile dev team can provide a resolution. Thank you.
They are aware of the request, thanks!

No problem
Please let us know if there is anything else!

Hi Elfving,
As per the previous recommendation from the nRF Connect for Mobile (iOS) team, it's best to raise a pull request for their dev team.
Would you be able to raise the pull request for me?
Your colleague, Tiago Monte, provided the Thingy:53 Sensor Hub project a few years back in a Dev Zone blog ( https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/thingy-53-sensor-hub).
This would help to complete the project and would be quite useful to existing and new Thingy:53 customers.
Here are the screenshots from nRF Connect for Mobile (iOS) connected to the Thingy:53 running Sensor Hub application:

Here's the required Thingy:53 UUIDs that need to be added for the Thingy:53 Sensor Hub and the sensor characteristics (https://github.com/NordicSemiconductor/bluetooth-numbers-database).
